Oh sorry I missed that question.
Beowolfe is sorta correct
1) We treat any baby breathing at birth to be liveborn, others treat a baby that survives 5 days to be liveborn (this is how the Netherlands gets their rosy number)
Also the premature birth issue... the United States routinely attempts to save premature babies, which we do remarkably well on, but some nations have hard barriers on gestation age before they will try (good example, a woman with two babies, one 6 months, one two months, a problem is detected in the two months baby and is surgically corrected and placed back in... the United States can, and regularly does do these sort of things, others don't. Btw both babies made it)
Some nations even record premature babies that die as miscarriages. Differing standards there, but...
2) "Value of life"
Some of the metrics toss in a Socialist tilted "value of life" which is a modifier to the final result. Aka the median is 80 but the value of life modifer (example) can make it 85.
This comes out in some of the hard tilt leftist versions and is very misleading.
3) Some nations have very few military deaths
While statistically speaking our death rate in the area is very low it does nudge numbers due to lower age level of the military.
4) Regional Differences
Hot regions affect differently than cold, dry versus wet, and generally speaking the different groups in Europe are 'prepared' for their weather while the larger melting pot of America is not.
5) Food Differences
Cow versus fish explains US vs Japan, Wheat versus Rice, Oranges versus Mangos... the list goes on. Fact is we have more sugars in our foods as well thanks to the huge sugars subsidy.
6) Infranstructure
We have far more cars here than Europe does and less training for new drivers to boot. More miles of roads by far as well and longer commutes (driving wise). This means more accidents young and old.
When you change just the live birth issue the United States actually shoots up to #2 in the world, when you account for other issues it actually shows we are more free and live older if we don't die an unnatural death than all others.
Statistically there is 10k deaths a day so ironically 9-11 was a major impact as well. The median age that day must have been mid thirties to low fourties.
Interesting thing to look up: Still born and miscarriage rates of each nation. Btw some nations don't record miscarriage rates
Everything bad in the economy is now Obama's fault. Every job lost, all the debt, all the lost retirement funds. All Obama. Are you happy now? We all get to blame Obama!
Kemp currently not being responded to until he makes CONCISE posts.
Avogardo and Noir ignored by me for life so people know why I do not respond to them. (Informational)
